The dynamic evolution of the charm hadron in hot quark matter was studied in the framework of a mul-tiphase transport (AMPT) model. We first reproduced the open charm hadron D0pT spectrum in Au+Au collisions at (√sNN) =200 GeV by triggering the (c-c) production in AMPT, and then the elliptic flow of charm hadrons was described with different parton cascade cross sections. Charm hadron azimuthal angular correlations were pro-posed, and they are affected by the different parton cross-section parameter applied in the model, which can facili-tate our understanding of the loss of collision energy of charm quarks in hot quark medium and can stimulate fur-ther experimental studies.
